Connection structure for filtration device

Abstract

A connection structure for a filtration device, which relates to the field of filter technology, includes a main shell body, a mounting section and a switch section respectively assembled at two ends of the main shell body, and an installation section. When the switch section is toggled in one direction, the switch section drives the installation section to rotate and be inserted into a mounting hole on a refrigerator, an inlet and an outlet are correspondingly connected to a refrigerator pipeline, and water flows through the filtering component to filter out impurities. By using the above technical solution, the connection failure and water leakage issues are prevented and offering simple connection operation and quick assembly.

What is claimed is:

 a switch section ( 300 ) assembled at another end of the main shell body ( 100 ); and 
 an installation section ( 400 ) passing through the main shell body ( 100 ), one end of the installation section ( 400 ) being fixedly assembled to the switch section ( 300 ) and another end of the installation section ( 400 ) extending from the mounting section ( 200 ); 
 wherein, when the switch section ( 300 ) is toggled in one direction, the switch section ( 300 ) drives the installation section ( 400 ) to rotate and be inserted into a mounting hole on a refrigerator, the inlet ( 210 ) and the outlet ( 220 ) are correspondingly connected to a refrigerator pipeline, and water flows through the filtering component ( 110 ) to filter out impurities, and 
 wherein the switch section ( 300 ) includes: a housing ( 310 ), a stationary shaft ( 320 ) fixedly assembled onto the housing ( 310 ), a sleeve ( 330 ) rotatably assembled onto the stationary shaft ( 320 ), a toggle switch ( 340 ) arranged on the sleeve ( 330 ), a first gear ( 350 ) fixedly assembled onto the sleeve ( 330 ), and a second gear ( 360 ) fixedly assembled onto the installation section ( 400 ) and engaged to the first gear ( 350 ). 
 
     
     
       2. The connection structure for the filtration device according to  claim 1 , wherein the first gear ( 350 ) and the second gear ( 360 ) are arranged vertically; wherein, when the toggle switch ( 340 ) is toggled, the first gear ( 350 ) is driven to rotate in a horizontal direction, and the first gear ( 350 ) drives the second gear ( 360 ) to rotate in a vertical direction. 
     
     
       3. The connection structure for the filtration device according to  claim 1 , wherein an inner peripheral side of the first gear ( 350 ) is provided with a first protrusion section ( 351 ), and the sleeve ( 330 ) is provided with an insertion slot ( 331 ) for the first protrusion section ( 351 ) to be inserted. 
     
     
       4. The connection structure for the filtration device according to  claim 1 , wherein the housing ( 310 ) is provided with a travel slot ( 370 ) for the toggle switch ( 340 ) to toggle back and forth. 
     
     
       5. The connection structure for the filtration device according to  claim 4 , wherein a side of the toggle switch ( 340 ) is provided with a second protrusion section ( 341 ), and a side of the travel slot ( 370 ) facing the toggle switch ( 340 ) is provided with a snap-fit section ( 371 ) that is abutted against the second protrusion section ( 341 ). 
     
     
       6. The connection structure for the filtration device according to  claim 5 , wherein a side of the snap-fit section ( 371 ) that is abutted against the second protrusion section ( 341 ) is provided with a snap-fit surface ( 3711 ), and a side of the snap-fit section ( 371 ) that is opposite to the snap-fit surface ( 3711 ) is provided with a guiding slope ( 3712 ). 
     
     
       7. The connection structure for the filtration device according to  claim 4 , wherein a bottom of the travel slot ( 370 ) is further provided with a recessed section ( 372 ) to facilitate toggling of the toggle switch ( 340 ). 
     
     
       8. The connection structure for the filtration device according to  claim 1 , wherein the installation section ( 400 ) includes: a connecting rod ( 410 ) passing through the second gear ( 360 ), and an installation head ( 420 ) fixedly assembled to an end of the connecting rod ( 410 ) that is away from the second gear ( 360 ). 
     
     
       9. The connection structure for the filtration device according to  claim 8 , wherein the installation head ( 420 ) is provided with a protrusion ( 421 ) at a connection with the mounting section ( 200 ); the mounting section ( 200 ) is provided with a rib ( 230 ) in an arc shape that matches the protrusion ( 421 ); wherein, when the toggle switch ( 340 ) is toggled in one direction, the protrusion ( 421 ) is abutted against one end of the rib ( 230 ); when the toggle switch ( 340 ) is toggled in another direction, the protrusion ( 421 ) is abutted against another end of the rib ( 230 ).
